Abstract
The invention relates to a lead-based multivariant alloy electroplating anode, and in particular relates to an anode material of lead-based multivariant alloy for electroplating chromium. The invention solves the problems that through the improvement of an electroplating chromium anode material, the selection of a power supply is limited, the strength of an anode is low, the iron impurities are accumulated, the temperature of an anode region is quickly increased, and the like. The lead-based multivariant alloy electroplating anode is prepared by the following step of forming an alloy material by any two or all of tin, stibium and bismuth so as to prepare the anode, wherein the anode comprises the following specific components in percentage by weight: 5-10% of tin, 2-6% of stibium, 3-9% of bismuth and the balance of lead. According to the lead-based multivariant alloy electroplating anode, the temperature of the anode region is close to the temperature of bath solution, and excellent plating quality can be obtained.
Description
Technical field:
The present invention is a kind of galvanic anode, particularly relates to a kind of anode material of electrodeposited chromium of lead-based multi-component alloy.
Background technology:
At present, the anode that electrodeposited chromium uses normally: 1) pure anode lead, or contain the LY of antimony 6%～8%, must use the little power supply of ripple factor, anode need regularly be scrubbed, otherwise anode conducting property is poor.2) stanniferous 30%～50%, the LY of silver 1%, or the alloy lead anode of stanniferous 10%, and anode intensity is low, and when complicated shape were electroplated, it was yielding to make imitative type anode.3) ordinary steel is prone to produce the iron contamination accumulation, and the light district narrows down, and covering power is poor.4) graphite anode, positive column temperature rise fast, cause the thick ability of plating, the coating internal stress is big, binding force of cladding material is low.
The anode weak point of above in sum four kinds of electrodeposited chromiums is, power supply selectional restriction, anode intensity are low, iron contamination accumulation, positive column temperature are risen fast.
Summary of the invention:
The objective of the invention is through improvement problem such as it is fast that above-mentioned power supply selectional restriction, anode intensity are low to solve, iron contamination accumulation and positive column temperature rise to electrodeposited chromium anode material choosing.
The present invention realizes through following technical scheme:
A kind of lead-based multi-component alloy galvanic anode; Process anode by any two or whole three kinds of metals in tin, antimony, the bismuth and plumbous component alloy material, its concrete content is (weight percent): tin content 5%～10%, antimony content 2%～6%; Bi content 3%～9%, all the other are plumbous.
Adopt anodization of the present invention, positive column temperature and tank liquor temperature are close, can obtain good quality of coating.
Embodiment:
The electrodeposited chromium anode that the present invention adopts, the anode LY that any two or whole three kinds of metals are formed of serving as reasons in plumbous and tin, antimony, the bismuth is specially the plumbous surplus that is, tin content 5%～10%, antimony content 2%～6%, the LY that bi content 3%～9% is formed.Its fusion is cast as anode, or processes the alloy anode plate, or process the profiling anode by workpiece to be plated.
Below in conjunction with embodiment the present invention is done further description.
